Excellent wines, great staff! If you like Cab, make sure to try their 2007 Kit's Killer Cab. Delicious! Great spot for a picnic, you can bring your own food and drink their wine with the flavored almond pairing!
Buy the climber bag of wine... too awesome. :) The vibe is great and the decor is refreshing and entertaining.
